Hey folks, My Mac-Protools is down, so I need to do a serious commercial project, for the first time, on my Windows-Reaper rig. (normally I only use it for live performance) I need to change the tempo & pitch of various tracks. I know I can do the pitch with Reaper's excellent built-in shift-9 / Shift- 0 thing, and then glueing the regions, but I'm stumped on time-change. Also, I don't have all of the same plugins for VST as I do for TDM. Some of these tracks are not played to a grid. So Ideally, I'd like to adjust time "on the fly," in other words by using automation first and fine-tuning, then making the changes permanent later. - But a straight change will also work if that's all I have. ---------------------------------------- How would you do this? Do I need a third-party plugin? If so, which do you recommend? Right now, ease-of-use is more important than absolute quality. - THANKS.

A couple of ways to change tempo and pitch of individual tracks. For each track (or section if you split) you can right click open Item properties and enter values for both (make sure you use a good pitch algo like elastic). OR to do it more on the fly, hover over the end of an item and hold down the "Alt" key. Your cursor will change to a hand and you can stretch or compress to slow down or speed up an item. There is not per track automation for playrate, but there is one for the master track (entire song). Hope that helps.

In item properties there is a value for both pitch and playrate. So if you put in 1.1 it will increase the rate of that item by 10%. And yes, you can stretch/shrink each ITEM with the method I described and it will change the rate (then the actual value will show up in item properties).

Thanks, guys! This was very helpful. This is actually a hair easier than (I can't believe I'm saying this) than on Protools. The sound quality is also quite acceptable. Nice. I also see that there's a new "nudge" feature in 4.x * Thank God. Time to read up on that. - Mind you, Reaper still 'aint Protools when it comes to editing, but she's getting there!
